Opt for better mobile security

SLYNUMBER doesn't need your personal information
Unlike wireless service providers like AT&T, Verizon, or T-Mobile, SLYNUMBER only asks for the absolute necessary information to activate your mobile phone number, so any sensitive data associated with your personal number will remain private.

Your SLYNUMBER is not associated with sensitive data
Because SLYNUMBER does not ask for more information than necessary, sensitive data, like your social security and physical address, are not associated with your temporary mobile phone number, so you can remain more anonymous online.

Activate apps with ease of mind
All the sensitive information typically associated with your personal number is not relevant to your SLYNUMBER and is consequently kept safe from applications mining data and other sensitive information.

Protect yourself from hackers and scammers
By keeping your personal number offline and managing spam blocking through SLYNUMBER's app, you can create an extra layer of protection between you and hackers who attempt to mind sensitive data and information through phone numbers.
